Feature Request: Multiple pipelines?

[brandon-reinhart]

Rapier rust allows us to manage multiple independent simulations by creating more than one pipeline, populating their containers, and stepping them. This is great for creating several experimental frameworks that work simultaneously.

Bevy rapier is amazing in its convenience, but doesn't (afaik) expose the ability to instance pipelines.

This might be something to think about given the Bevy Many Worlds RFC: https://github.com/bevyengine/rfcs/pull/43

I definitely also need this. My use case is similar to Minecraft, where there are multiple game dimensions/worlds that are independent.

A possible workaround would be to just place these far apart, but that requires unpassable boundaries (perhaps buggy) and runs into issues with floating point precision.

This issue would be solved by #328
